In a family lived father mother and a child. Parents used to scold him for printing his hand print with painting colors all over the walls of house. One day kid gave a handmade card to his parents. When parents got the card they saw there was a little hand print of their son on card. Inside there was a photograph of him with a little note writing with his photo. Words written were " Sometimes you get angry and discouraged because I am so small and leave my fingerprints on furniture and walls. but am growing everyday and some day these finger prints will fade away. so, here is put a final hand print of my hand here on card so that one day you can recall how my fingerprint exactly looked when I was small."They realized what they have been losing in the race of life and this touched heart heart and they hugged and kissed him with love. 
Don't wait to spend time with kids. Slow down and enjoy and spend with family. Once time pass away you will not get that back and its better to enjoy life now then to regret later.
